SPECIFICATION forming part of Letters Patent No. 781,394, dated January 31:1905. i Application filed April 25, I904. Serial No. 204,670. 7

' To all whom it may concern.-

gan, county of Cheboygan, State of Michigan, have invented a certain new and useful Improvement in Snow-Flows; and I declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. My invention relates to snow-plows; and i consists in the various combinations hereinafter described and claimed.

1n the drawings, Figure l is a perspective view of the snow-plow fully assembled with the exception that the tongue and'appliances by which the same are drawn is omitted, they constituting no part. of the invention. Fig.

' 2 is a reverse perspective view of the forward plow or scraper detached from the main beam. Fig. 3 is a detail of'the construction. showing how the main beam is tilted from side ,to side. Fig. 4: is a. detail perspective view of one of the wings and mechanism for controlling the same. Fig. 5 is a detailview showing the operative apparatus for raising and control-' ling the front plow oriscraper illustrated in Fig. 2. Fig. 6is apartial rear view of the machine, the wings being omitted.

In the drawings similar letters refer to similar parts. 1

In the drawings, A represents a platform,

I upon which the operator takes his stand in the position indicated at A. i

B is a main beam, the lower edge of the rear end of which is attached to the central part of the platform A by meansof the hingestaples or hinges b b. This permits it to tiltto the sector being widened and toothed, as

shown at d. The sector itself has a corresponding series of teeth 0. which engage with the teeth d of the lever D, and by swinging the lever D from side to side, the teeth being in engagement with and the sector C being the beam B is tilted or rotated along a longitudinal axis corresponding with its lower edge and that this tilting or rotation carries with it any attachments attached to it and that the degree of rotation can be modified by the operator at will. i

The sector 0 is slotted at O. A hand-wheel carrying a screw which threads into the top of the beam B forms a set-screw whereby the holding or setting of the inclination of the beam B can be fixed, and as a set-screw of this kind is old and familiar it need not be particularly described or illustrated. It is obvious, however, that any one of a variety of attachments, as a sector with teeth and a latch attached to D, could be employed for the purpose of rigidly'hclding the beam B in any position within the limits of its movement.

The forward central plow or scraper illustrated'in Fig. 2, having two wings E E, engages the beam B by a central slot 6, in which the beam is located, and two rearwardlyextending rings E E, closely engaging the-opposite sides of the beam and braced by appropriate braces e c. The slot 6 does not extend vertically entirely across or through the wings E E, but a continuing portion is left underneath the beam B, uniting the two ends. A sharp metallic edge is attached to the lower edge of the wings E E,forming a cutting edge. The wings E E are preferably located at some held rigidly to'the platform, it is obvious that other than a right angle to the beam B. At-

tached to the wings E E" are vertical ratchets Gr G, one upon either side of the beam B.

A shaft H, journaled in and through the beam B, carries upon each end thereof a pinion J, each pinion being adapted to engage in each rack Gr G. A sprocket-wheel J is also attached to the same shaft, and a sprocket-chain K runs over this sprocket wheel and back to" another sprocket wheel, K, attached to the shaft passing through and journaled in the rear of the beam B. Upon this lower shaft is also fixed a hand-wheel K whereby the sprocket-wheel may be rotated, and through the intervention of the chain the pinions J J are also rotated, thus permitting the elevation 0r lowering of the wings E E, and in order to hold them at any desired elevation I employ the means shown inFig. 5, viz: Upon the opposite end of the shaft, carrying a sprocketwheel K and its auxiliary hand-wheel K, I have attached another wheel, L, with notches therein. A bell-crank lever M has projections m upon one end thereof adapted to engage in the notches in the wheel L and is normally held in engagement therewith by means of the spring S. This lever is journaled also in the beam B, and it has an angular foot-piece L, whereby the lever can be rotated and the projections m withdrawn from the wheel L, thus permitting the hand-wheel K to be rotated.

Underneath the platform A and upon either side thereof is a runner R. The front of the machine is also supported by another runner, R. The bottom edges of these runners have narrow sharp longitudinal metallic flanges projecting slightly from the lower edge of the bottom or level frame of the runner. The ofiice is to prevent a side motion or slipping of the runner, the sharp edges binding or cutting into the snow underneath. All the runners are so constructed. Attached to the outside runners R is a wing W, the forward end of the wing being hinged thereto by the hinges Y. They therefore can lie up close to the runner R or by means of the mechanism hereinafter described be swung outward therefrom at an angle thereto, as shown in Figs. 1 and 4. Pivotally attached to the rear side of each wing is a brace W, the free end of which has a slot to, through which a lever N projects. This lever N is pivoted at a to the runner R and is held in proper engagement therewith by means of bracketed slot P. By drawing the upper end of the lever N forward the brace is brought nearly or quite longitudinally with reference to the runner R, thus bringing the wing W in close contact therewith. By drawing the lever in backward the wing W is forced outward and the swinging arm WV becomes a brace, holding it rigidly in that position, as shown in Fig. 1.

Inasmuch as the Wings E E are only vertically movable with reference to the beam B, but must be tilted therewith, it is obvious that by tilting the beam B the central portion of the road cut by the wings E E can be out upon a different plane from the outer portions cut by the wings W IV or the wings E E can-be raised entirely above the line of cutting of wings WV W, so as to leave a raised center. On the other hand, the wings E E may be lowered below the cutting edges of the wings IV IV, so that the center of the road may be cut deeper than the sides and at a different angle. It is also obvious that the width of the cutting on each side of the middle with the wings W IV can be varied according to the extent to which the free end of the wing W is thrown outwardly by operation of the lever N. It is also further obvious that the runner R, pivoted to B and shown as a single runner, may be replaced by a bobsled With two runners.

A seat T is shown for the driver.

Having thus described my invention, what I claim is- 1. In a snow-plow, the combination of a carrying-platform A, having runners, a longitudinally arranged, but transversely tilting beam B. and means whereby the tilting of the said beam may be controlled, substantially as described.

2. Ina snow-plow, the combination of a carrying-platform A, having runners, a longitudinally arranged, but transversely tilting beam B, means wherebythe tilting of said beam may be controlled, and wings E, carried by said beam, substantially as described.

3. In a snow-plow, the combination of a carrying-platform A, having runners, a longitudinally arranged, but transversely tilting beam B, means whereby the tilting of said beam may be controlled, wings E carried by said beam and vertically adjustable with reference thereto, and means for controlling such vertical adjustment,substantially as described.

4. In a snow-plow, the combination of a carrying-platform A, having runners, at longitudinally arranged, but transversely tilting beam B, means whereby the tilting of the said beam may be controlled, wings E carried by said beam and vertically adjustable with reference thereto, means for controlling such vertical adjustment, and the wings adjustably attached to the runners It, substantially as described.

5. In a snow-plow, the combination of a platform, runners adapted to carry the same, a beam longitudinally hinged thereto, an arch passing over said beam, and means connected with the said beam, whereby the tilting thereof may be controlled by said arch, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
